About the Airtac SAI63 Standard Cylinder SAI63X270
The AirTAC SAI63X270 is a double-acting ISO 15552 profile cylinder engineered to deliver a robust 1559 N of push force at 0.5 MPa. Its extruded aluminum barrel design omits tie-rods, providing a smooth exterior that simplifies cleaning and sensor placement. A 270 mm stroke makes this unit well-suited for mid-range linear actuation tasks requiring substantial reach and power.
Beyond the standard specifications, this configuration utilizes a durable carbon steel piston rod and features G3/8 PT tapered port threads for a secure pneumatic connection. The barrel incorporates dual sensor grooves, allowing for straightforward installation of CMSE or DMSE switches if position feedback is later required by adding a magnet.

Where the Airtac SAI63 Standard Cylinder SAI63X270 Is Used
Automated Clamping
Provides the 1559 N push force required to secure heavy metal castings during CNC machining operations.
Package Diverting
Utilizes the 270 mm stroke to push heavy pallets or cartons smoothly across transfer stations.
Material Lift
Raises and lowers medium-weight platform assemblies in automated assembly lines with reliable double-acting power.
Is the Airtac SAI63 Standard Cylinder SAI63X270 the Right Cylinder?
Selecting this 63 mm bore cylinder is ideal when a machine requires upward of 1559 N of thrust at 0.5 MPa, bridging the gap between the 982 N output of a 50 mm bore and the 2513 N capacity of an 80 mm bore. Because the 270 mm stroke exceeds 300 mm, designers should evaluate potential side loads; utilizing an external guide rail or a guided cylinder helps prevent rod-bearing bending and premature wear.
For ISO 15552 mounting interchangeability, ensure your fixture matches the standard mounting accessories like the LB foot or TC trunnion. Note that this standard SAI variant relies on adjustable air cushions at both ends to decelerate the piston smoothly; it does not hold position if air pressure drops. If your application requires static holding under lost pressure, consider the SAIL lock variant or an external pilot-operated check valve.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
